APPARATUS FOR CLEANSING, 'CONDENSING, AND WASHING GASES.

JEECIFlCATION forming part of Letters Patent No. 306,676, dated October14, 1884.

(No model.)

T 0 all whom, it may concern:

Be it known that 1, James CRUTOHETT, a subject of the Queen of GreatBritain, residing in the city, county, and State of New York, haveinvented certain new and useful Improvements in Apparatus for \Vashing,Condensing, and Cleansing Gases; and I do hereby declare the followingto be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make anduse the same, reference being had to the accompanying drawings, and toletters of reference marked thereon, which form a part of thisspecification.

My invention relates to a special construction of apparatus for washing,condensing,

and cleansing gases, and it is more especially intended for use in thetreatment of gases for illumination, though applicable for treatingother gases, if desired, and the apparatus is adapted for connectionwith the cupola or other part of the gas-generator or furnace in whichthe gas is manufactured, so that the gas as made may pass directly intothis cleanser.

Figure 1 is a sectional view of the apparatus,iand Fig. 2 representsdetail views of the rods used in the washing-cylinder.

The drawings illustrate my invention as applied to the cupola or towerof a gas-generating apparatus, whether for illuminating, for heating,for motive power, or for other purposessuch, for instance, as that shownin my application for a patent filed November 30, 1883, which will serveby way of illustration.

A represents a longitudinal view of an apparatus embodying my invention,a portion of the casing being broken away, the better to display theinterior. A cylindrical chamber, 1), for holding water and gas, inclosesa revolving cylinder, 0, whose shaft (Z has its bearings in the ends ofthe cylinder. Radial rods 0 are secured from end to end on thisrevolving cylinder, projecting from it all around its circumference.These rods may be inserted in the cylinder, or may be fastened to it inany desired manner, and they sh ould be small and numerous,somewhat likethose of a brush. The rods may project from twelve to eighteen inchesbeyond the cylinder, and may in their crossseetion be either round,flat, or angular, and of metal or any other material having sufficientdurability. If desired, their extremities may in some cases be made withflat or broad surfaces, and with their extreme edges serrated orcorrugated to effect a more complete action on the gas; or these rodsmay have barbs or irregular projections placed on them for the greaterpart of their length at inter vals or intermediate points between theirextremities and the points or places of connection with the shaft, asshown in Fig. 2, and all the rods may be connected together by a wirenet-work or wire fastenings, as also shown in Fig. 2, this net-workconnection being at or near the extremities of the rods or at otherpoints on the rods, and serving to bind and strengthen the whole andmore thoroughly agitate the water and gas. The radial rods 01' wiresshould extend-from their cylinder to (as nearly as practicable) theinner face of the chamber 1) without touching'it, in order to 0p crateequally when the cylinder revolves upon substantially the whole body ofthe gas admitted to the chamber and passing through it, and

within the chamber a supply of water is kept, as indicated by the dottedlines m x, and into which the rods, when in action, enter as theydescend, and from which they emerge as they rise again, and wherebyevery one of the rods or wires operates upon and serves to cleanseand-wash the gas to the extent of its surface and friction, the wholeseries of rods serving to cleanse uniformly the whole body of gas twithin the case, because the revolving cleansing-cylinder practicallyfills the case,with only enough space or clearance around it to permitits revolutions, and at the same time all the rods or wires are freefrom any liability of becoming clogged at their surface, and are leftfree to be revolved continuously without any impediment arising withinthe chamber. The water may enter at f, and be controlled by a cock, 9,and be discharged with its impurities by a cock, h, into any appropriatevessel by siphons or valves, as desired or preferred. The impuritiesleave the cleansing-chamber with the continuous run and change of water.The washed and cleansed gas leaves the chamber by any appropriateexit-pipe, i.

The barbed pieces or projections may be placed and secured on the rodsin any convenient manner-as, for instance, they may have central orother holes, and be threaded like I eomplish.

beads upon the wire and held to place by-a nut or other simple means.lhe case being cylindrical, instead of square or oblong, incrossseetion, permits the rods of the revolving cylinder to act upon thewhole body of gas from center to circumference. The cylinder and itsrods, reaching as they do from end to end of their inclosed ease,leaveno space in which the washing-cylinder does not act on the gas; nor doesmy construction involve the need of a system of cylinders one aboveanother that one may aid in perlbrming the duty that the othersindividually can but imperfectly ac- In my construction and arrangementof casing and cylinder one cylinderperforms the whole duty required.

I claim- 1. In combination with a horizontal ease, as described, arevolving gas-cleanser within such case, provided with a system ofradial rods having thereon sets of barbs or irregular projections at ornear their extremities, and also smaller sets at points between suchextremities and the axis or shaft of such eleanser,substantiall y as andfor the purpose set forth.

In combination with the revolving eylinder and its inelosingeasinghaving inlet and outlet pipes at its opposite ends, the radial rods onsuch cylinder, and wires connected to and serving to unite theextremities or other parts of such rods, substantially as set forth.
